Automatic cleaning robot

ABSTRACT

An automatic cleaning robot includes a cleaning machine body, at least one water tank or at least one dust collecting box, and at least two rotating elements embedded on a bottom of the cleaning machine body. The cleaning machine body is disposed with an accommodating space for placing the water tank or the cleaning machine body, and inside the accommodating space is disposed with a sensor switch and at least two diversion holes extending to the bottom of the cleaning machine body. A sensor and water outlets corresponding to the diversion holes are disposed on the water tank. When the sensor switch senses the sensor, it means the water tank is disposed in the accommodating space, and the cleaning machine body injects air into the water tank through a conduit to cause the water in the water tank to drop on the rotating elements through the diversion holes.

BACKGROUND OF THE INVENTION Field of Invention

The present invention relates to an automatic cleaning robot and more particularly to an automatic cleaning robot that can be switched to a vacuuming function or a mopping function.

Description of Related Art

The automatic cleaning machines on the market can be roughly classified into two types, i.e. sweeping robots and mopping robots. The sweeping robot sucks the dust and trash through vacuuming from a place where the sweeping robot passes through into a dust collecting box, while the mopping robot uses the water in an internal water tank to soak and wet a mop, so as to use the mop to perform mopping when the mopping robot moves.

Because the sweeping robot and the mopping robot are completely opposite in the principle of action, at present, the sweeping and mopping two-in-one automatic cleaning machine on the market installs the sweeping mechanism and the mopping mechanism at the opposite front and rear end of the cleaning machine respectively. It is expected that the cleaning mechanism at the front end will first perform vacuuming during the moving process of the cleaning machine, and then perform mopping with the rear-end mopping mechanism. However, the cleaning machines designed in this way must be very precise in terms of path planning and angles of movement (rotation). Otherwise, the mopping mechanism will drag across the unswept floor, causing the situations where dust is soaked in water and difficult to be sucked into the dust collecting box, and even the dust is directly adsorbed on the mop, causing the places that have been mopped to become dirty instead.

SUMMARY OF THE INVENTION

In order to solve the technical problems of the prior art, an object of the present invention is to provide an automatic cleaning robot that integrates the functions of sweeping and mopping on the same machine and the functions of sweeping and mopping do not interfere with each other.

In order to achieve the above object, the automatic cleaning robot of the present invention mainly comprises a cleaning machine body, a water tank, a dust collecting box, and at least two rotating elements. The cleaning machine body at least comprises an accommodating space and a motor, wherein the water tank and the dust collecting box can be disposed in the accommodating space, the motor extends into the accommodating space with a conduit and penetrates into the water tank or the dust collecting box, and the two rotating elements are embedded on a bottom of the cleaning machine body and rotate when the automatic cleaning robot of the present invention is displaced.

Wherein the cleaning machine body is disposed with at least two diversion holes on a wall surface of the accommodating space that extend to the bottom of the cleaning machine body and are respectively located above the rotating elements, and a valve is disposed between the accommodating space and each of the diversion holes.

Wherein the water tank is disposed with at least two water outlets, and the positions of the water outlets correspond to the positions of the diversion holes respectively, and a sensor switch is disposed on an inner wall surface of the accommodating space, and an sensor is disposed on an outer wall surface of the water tank for the sensing of the sensor switch.

In addition, the rotating elements are dust collecting brushes or cleaning cloth structures.

The above-mentioned cleaning cloth structure at least comprises a shaft, a base and a cloth sleeve, wherein the bases are connected with the shafts, and each of the bases is disposed with at least one perforation penetrating a top surface and a bottom surface of the base, and the cloth sleeve is wrapped around an outer surface of the base.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention is exemplified and explained by the following embodiment, but the present invention is not limited by the following embodiment.

Please refer to FIG. 1, which is a schematic diagram of a sweeping structure of an automatic cleaning robot according to the present invention. When the automatic cleaning robot performs sweeping, a dust collecting box 3 is disposed inside an accommodating space 11 of a cleaning machine body 1, a conduit 15 connected to a motor (not shown in the Figure) is extended into the dust collecting box 3, and then a dust collecting brush 16 is embedded at a bottom position of the cleaning machine body 1 below a diversion hole 12. Then, the automatic cleaning robot of the present invention is started and let the automatic cleaning robot starts to move itself according to the built-in displacement path and rotates the dust collecting brush 16 to sweep dust or trash below the automatic cleaning robot. At this time, since a sensor switch 111 of the cleaning machine body 1 has not sensed a sensor, the cleaning machine body 1 drives the motor to evacuate the dust collecting box 3 through the conduit 15 to produce suction, and the automatic cleaning robot uses a bottom suction port (not shown in the Figure) to suck dust and trash into the dust collecting box 3.

Referring to FIG. 2, when the automatic cleaning robot of the present invention wants to perform mopping, the dust collecting box 3 is removed from the accommodating space 11, and a water tank 2 is disposed inside the accommodating space 11 of the cleaning machine body 1. A sensor 22 disposed on an outer surface of the water tank 2 is corresponding to the sensor switch 111 on an inner wall surface of the accommodating space 11, and a water outlet 21 disposed on the water tank 2 is corresponding to the position of the diversion hole 12 on the wall surface of the accommodating space 11. The conduit 15 connected to the motor (not shown in the Figure) is extended into the water tank 2. Then the dust collecting brush 16 is removed from the cleaning machine body 1 and a cleaning cloth device 14 is embedded at a bottom position of the cleaning machine body 1 below the diversion hole 12.

Then, the automatic cleaning robot of the present invention is started and let the automatic cleaning robot starts to move itself according to the built-in displacement path. At this time, the sensor switch 111 senses the sensor 22 and opens a valve 13 to make the diversion hole 12 to connect with the water outlet 21, and the motor is activated at the same time so that the motor feeds air into the water tank 2 through the conduit 15, and therefore the water in the water tank 2 is pressurized and flows out from the diversion hole 12 through the water outlet 21, and drops on a cloth sleeve 144 of the cleaning cloth device 14. Water starts to spread from a position of the cloth sleeve 144 where the water is dropped at to wet the cloth sleeve 144. At this time, the cleaning cloth device 14 is driven by a shaft 141 to rotate when the automatic cleaning robot moves. Mopping can be performed through the soaked cloth sleeve 144 during the moving process of the automatic cleaning robot. In addition, since a base 142 of the cleaning cloth device 14 of the present invention is disposed with perforations 143 penetrating through a top surface and a bottom surface of the base 142, when the cloth sleeve 144 is fully soaked and saturated with water, excess water will flow from the perforations 143 onto the cloth sleeve 144 at a bottom of the base 142 and flow to the floor to prevent the excess water from splashing when the cleaning cloth device 14 rotates.

From the above, the automatic cleaning robot of the present invention uses the sensor switch 111 to sense whether the water tank 2 or the dust collecting box 3 is disposed in the accommodating space 11 in order to control the motor to perform the action of extracting or exhausting air. By replacing the dust collecting brush 16 and the cleaning cloth device 14, the automatic cleaning robot of the present invention can integrate the sweeping and mopping functions on the same machine. And through the replacement of the water tank 2 and the dust collecting box 3 to produce designs with different functions, the interference between the sweeping and mopping functions can be avoided; otherwise causing the situations in the conventional techniques where the dust is soaked in water and difficult to be sucked into the dust collecting box 3, or the dust is directly adsorbed on the mop, causing the places that have been mopped to become dirty instead.
